Add a isvalditated bool column to your users table with a default value of 0. When you create the user set an md5 hash of the username and dart or something to generate a random string. Save that somewhere ( another column in the users table If you wish). Have the link go to a validate page that checks the userid with the string and if it matches set isvalidated=1.  
I usually create another field in the user-table named "verifyed" and another field called "verify_code".

Verify is set to "0" upon creation. And "verify_code" contains a 10 character randomly generated code.

When I send the user the activation mail. I insert a link like:

The the activation.php query's my user-table with the code, and if username and code matches, it sets the verifyed to "1".
